Highlights
Course Overview
Led by some of the best consultants on the planet, this course is aimed at .NET application developers who would like to gain important advanced skills to help them develop and support their applications more efficiently and productively.
The course instructors are hand picked to ensure they can add value to the most demanding developers..
The programme is made up of 3 days Performance and 2 days debugging. Each part can be taken separately, if required.
Improving the Performance of .NET Applications
In this three day instructor-led course you will become acquainted with performance measurement tools, including profilers, ETW, and performance counters. You will use these tools in a series of practical hands-on labs to improve the memory allocation patterns, GC behaviour, and – of course – speed of .NET applications. Together with practical information on performance measurement, the course delivers deep internal knowledge of the CLR, focusing on type internals, garbage collection, unsafe code. Armed with both theoretical and practical knowledge about the CLR, you will be able to measure and systematically improve the performance of your .NET applications.
Target audience: experienced C# or VB.NET developers

Debugging .NET Applications
In this two day instructor-led course you will learn about all the ways to debug your .NET applications in development and in production. You will explore and practice the process of creating crash dumps, analysing them, and obtaining the root cause for exceptions and hangs. You will also experiment with more difficult problems, such as memory leaks, deadlocks, and finalisation-related bugs. At the end of the course you will be equipped with the knowledge and tools to debug .NET applications in the field, and improve your debugging experience during development as well.

"Our tailored course provided a well rounded introduction and also covered some intermediate level topics that we needed to know. Clive gave us some best practice ideas and tips to take away. Fast paced but the instructor never lost any of the delegates"
